Parallel robots have often been used during the last decade because of their advantages,
such as: good dynamic behavior, easiness of inverse kinematics, and higher accuracy etc. Despite
those advantages, parallel robots are criticized in relation to their small work space, and not really
modular topology and complex mechanical architecture. Industrial experience has realized that the
major disadvantage of parallel robots is the small dimension of work space. Strong economical
reasons and all technical advantages of parallel robots recommend these robots to do tasks that are
proper to machine tools.
